Abrasive SpongeBob (Netflix Smash Bros.)

Abrasive SpongeBob, often called Abrasive S.B. for short, is the evil clone of SpongeBob, a major member of the Bunnitan Army and the overall tertiary antagonist of the Netflix Smash Bros. series as well as the secondary antagonist of The Netflix Smash Bros. Movie. Abrasive S.B. originates from The Abrasive Side, a SpongeBob episode that follows SpongeBob gets an abrasive side so he can say "no", but it eventually starts to take over his personality. His NSB incarnation is a character all by itself and his Final Smash doesn't change in Universe. While Abrasive S.B. plays a minor role in the episode, he plays a far more evil role as an evil creation of Lord Boiyoing out to destroy SpongeBob for the good of evil in the Netflix Smash Bros. series.

Abrasive S.B.'s personality is the complete opposite of the personality of the normal SpongeBob. While SpongeBob is kind and caring, Abrasive S.B. is a complete jerk to anyone he encounters, usually by insulting them or beating them up. While SpongeBob has interests in a lot of things, Abrasive S.B. has no interests in anything whatsoever, except evil plans from Lord Boiyoing. He is also relentless to destroy SpongeBob.

Abrasive S.B. is supposed to represent the typical abrasive side of a sponge, which is used to get rid of tough stains. Instead of small eyelashes, he has a big black bushy monobrow that makes him look like a grouch.
